Dear Prof. Duan,

If you take a look at our RHMHM School publication on Externetworks on www.researchgate.net/profile/Soumitra_Mallick on which S.K.

Mallick, S.Raychaudhury, S.Mallick, are the principal investigators, the RHMHMINFine Structure Constant has been computed to be 4*10^3/c(in vacuum), which is also the Yang Mills Gap and along with the four laws of Systems Physics we have discovered (String Matching Field which also solves the Millenium Prize problem) with AGGNNNetworks and Higgs-Mallick mechanism for the Fundamental String Matching Field model and by lowering of dimensions by DBranes Functor Algebra Calculus induced Vector Diffeotopy of Embeddings "jump quantum conductance" (Mallick, Hamburger, Mallick (2016, 2017, 2018),Mallick (2018), has the Quantum Mechanical Vectorial Mechanical Resultant force of Newtons dimensional cooling (Mallick et. al.) which with the Functor Algebra Calculus embedding of higher dimensional AGN research of Raychaudhury et. al. string condenses by systems classification and string condensation in the RTP Classical Field which is our country specific average temperature and pressure normally (current) with stable population birth and death processes (Mallick (2014)). Hence the stability of Temperature and Pressure at the sea level functorally (databased hence entropically) (Mallick (1993, 2009)) depends on the degree of environmental networking including of course both natural and artificial networking with the string perturbation and string condensation achieved through the degree of AGGNNNetwork adaptation by cybernetic networking and natural environmental networking by "green policies". This is a quantum science result using string theory and the natural resonance achieved through networking with Vector Diffetopy Embedding in the Externetwork four dimensional "reduced relativistic genetic "learning" and growth field". I cannot give you a more quantified answer than that but that is the application of our research so far which I could apply to your question. Hope itis of some help in clarifying issues. Given the size of the atmosphere the potential reservoir of integration of the atmospheric field depending on the area of application of the AGGNNNetwork systems integration can be calculated at the above rate and hence the operation of the RHMHM School HM(YM) cooling. Because of the Pvs.NP problem which we have solved by "jump quantum conductance" for transitivity of our field the mechanics requires quantum chemistry for application as also the engineering management of the problem.

Global warming will likely rise to 1.5oC above pre - industrial levels between 2030 and 2052 if warming continues to increase at the current rate. The report says that limiting to below 1.5oC global net human - caused emissions of CO2 would need to fall by about 45 percent from 2010 levels by 2030, reaching " net zero" around 2050.( i.e keeping total cumulative emissions within a carbon budget ). Even just for limiting global warming to below 2oC, CO2 emissions should decline by 25% until 2030 and by 100% until 2075. For more details consult https://en.wikipedia.org -wiki - special

As soon as the ice melts in the Arctic and thawing of permafrost in Siberia begins, strong carbon emissions into the atmosphere will occur (emissions will happen heating anddecomposition organic matter in the soil) - they cannot be prevented or blocked.

Only one way out - humanity needs to adapt.

Well, despite adaptation sounds pessimistic, but that's probably what we could do.

Despite the hand shaking and back slapping, the Katowice Climate Summit only succeeded in kicking the can down the road in preparation for discussing global warming mitigation measures without resolution at the next meeting. Our politicians cannot reconcile the needs of the present (ensuring continued national economic well-being and getting re-elected) with those of the future (eliminating poverty and preserving the planet). It is an immense issue and one which I feel will be resolved eventually but only once the global temperature has risen above the 1.5C limit.

Of the negative emission technologies, biomass energy with carbon capture and storage (BECCS) seems the most technically feasible. To provide meaningful CO2 reduction, there has to be a lot more biomass produced (local to available CO2 storage) and this means more land for forestation. An area the size of India is estimated, which will compete with space for growing crops. Also, as meat production requires a lot more space than growing vegetables, eating beans in preference to meat will help free space. So, for BECCS to proceed, there has to be a radical change in land usage as well as in our diets.

As for adaptation, that is easier said than done. Trees will die off as their growing environment disappears as, unlike humans, they do not have the option of upping their roots and moving to a more acceptable growing region/environment. Unless man transplants them, they will not seed themselves in the new region as previously they were not present there. Similarly, if Antarctica heats up to where do the penguins move? The rate of evolution is much slower than the change in climate so there will be widespread extinction of flora and fauna, all casualties of climate change.
